Do you test with Luatex? The output with Luametatex is correct but Luatex creates a raised bar (and different linebreaking). Wolfgang

As you suggested, I will give a try to LMTX but be aware most user still use MKIV until most distros upgrade the texlive version of context to LMTX. Regards, Xavier

As you suggested, I will give a try to LMTX but be aware most user still use MKIV until most distros upgrade the texlive version of context to LMTX. It's not that hard to install lmtx alongside. If distributions take from texlive then likely you also end up with files that are not needed (base
Not really. It's a a bug in the fonts (that will stay if only for compaibility reasons). There is a catch in mkiv that compensates for it but only when characters are not there. So, for these two I now force the catch. In lmtx we have a bit different approach: we just assuem they are wrong in all fonts and fix them or replace them. We also have a more advanced math engine so we can control placement better. There are also 'font parameters' involved that can be bad (i guess that designers can't really test math font parameters). In lmtx we have more of them, beyond what opentype math provides. All of this is handled in goodie files. That mechanism is present in mkiv but no one ever bothered to spent time on it. That said: the last two years Mikeal and I spent a *lot* of time on math and we don't really look back at mkiv / mkii also because there is way more neat things now (most probably go unnoticed) ... you can read about it in some documents that come with context, articles in tugboat, and there are talks by Mikael at tug meetings on YT. package) and lack some fonts (esp math) by default. You'd also benefit from the last couple of years advancements. Keep in mind that for a long term tex (document) project a snapshot approach is healthy because you never know what a distribution adds / replaces (esp fonts can be a mess and you want to know what you use).

What do you run directlua in LMTX? in this case, what does does lualibs-os provide? os.resultof is built into context so that should just work
ok, i did as search on ctan and it looks like that lua file is just the context l-os one renamed so no need to load anything, in fact, loading it might even break the built in when it does overloads Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
Hi,
On Sun, Aug 13, 2023 at 9:13 AM Xavier B.
So,
Finally is it a bug in MKIV? It seems you fix some kind of bug in your messages. Is it true?
The output with Luametatex is correct but Luatex creates a raised bar (and different linebreaking).
\showglyphs
\startTEXpage[offset=1ex] \ruledhbox{$\overline {OA} = \overbar {OA} = 4.2$} \par \ruledhbox{$\underline {OA} = \underbar {OA} = 4.2$} \par \ruledhbox{$\widetilde {OA} = \widebar {OA} = 4.2$} \par \ruledhbox{$\overbracket {OA} = \underbracket {OA} = 4.2$} \stopTEXpage
I'll add a 'force fix in spite of extensible being present' in mkiv. In lmtx we always fix also because we drop in nicer shapes (watch the round tips in lm and fancy tips in antykwa) and concluded that fonts will remain as they are.
Hans
As you suggested, I will give a try to LMTX but be aware most user still use MKIV until most distros upgrade the texlive version of context to LMTX.
Regards, Xavier
One can also try to instead use the accent mechanism instead of a stacker: % engine=luatex \definemathtopaccent[widebar] ["0305] \startTEXpage[offset=3pt] $\overbar{OA}$ $\widebar{OA}$ \stopTEXpage The \widebar is defined (almost) like that in lmtx. /Mikael
